+          This option enables kernel support for the Vector Scaler extensions
+          to the PowerPC processor. The kernel currently supports saving and
+          restoring VSX registers, and turning on the 'VSX enable' bit so user
+          processes can execute VSX instructions.
+
+          This option is only useful if you have a processor that supports
+          VSX (P7 and above), but does not have any affect on a non-VSX
+          CPUs (it does, however add code to the kernel).
